10. Excellent balance car performance
The car uses Kalman filtering algorithm, serial PID algorithm, smoothing filtering algorithm, two spin algorithms, and dynamic center of gravity algorithm. High performance energy comes from better algorithms, giving the car better balance performance.
Balance performance testing

Attitude recognition: When the car is placed on the ground, it recognizes this action through corresponding algorithms and automatically activates the balance system. When the car is lifted vertically while standing upright, and then placed horizontally, the algorithm recognizes this action and automatically shuts down the balance system, causing the motor to stop rotating.
